ORE-CONCENTRATOR.

SPECIFICATION forming part of Letters Patent No. 300,479, dated June 17,1884.-

Application filed December 13, 1883. (No model.)

To all whom it may concern:

Be it known that we, WILLIAM B. KENNE- DY and lia son M. Nnsnrr, both ofSilver Reef, in the county of W'ashington and Territory of Utah, haveinvented a new and Improved Ore-Concentrator, of which the following isa full, clear, and exact description.

Our invention consists of an improved contrivance of ore-concentratingapparatus, whereby the washing, concentrating, and separating of theores will be more effectually accomplished, and the concentrates removedfrom the sluiceway to better advantage and more expeditiously thanheretofore, all as hereinafter fully described, and specifically setforth in. the claims.

Reference is to be had to the accompanying drawings, forming part ofthis specification,

concentrator, and Fig. 2 is a longitudinal sectional elevation of thesame.

In any suitable long box or sluiceway, a, we arrange a series ofagitators, b, and governors 0 along the upper part of the same, andanother series of wings, cl, along the lower portion of the same, toform eddies and whirlpools to effect the concentration and deposit ofthe ore. Before each agitator b an eddy is formed which effects depositsat 6. Between each agitator and governor a whirlpool is caused, whicheffectually washes and concentrates the ores, and between the lowergovernor and the upper wing, and also between the wings, eddies areformed at f, where the finer concentrates are deposited. XVe connect allthese devices detachably, so that they may be removed to enable theconcentrates to be washed out of the slniceway at the lower end intosuitable receptacles, instead of shoveling them out in different pilesalong the sluiceway. The said devices may be connected in any approvedway for being detached; but a simple way is to connect the agitators andthe wings by hasps 7:, attached to them, and staples 5 attached to thebottom or sides of the sluiceway, and the governors may be sus pendedfrom cross-bars i, on the top of the ing provided with apertures toengage the keys, whereby said bars may be adjusted up or down to set thegovernors higher or lower, according as they are required to be, forregulating the flow of the water, said governors consisting of gateswhich regulate the flow according as they are set higher or lower.

The agitators consist of partitions a little shorter than the width ofthe sluiceway, and are set down on the bottom, so as to prevent the flowof water except at the ends of the partitions, which causes eddies infront and whirlpools behind the agitators.

The wings consist of plates not quite as long as the width of thesluiceway, which are detachably connected to the opposite sides of thesluiceway, and point diagonaliy across the sluiceway in an upwarddirection suitable for forming eddies above them.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is

1. The combination, with a sluiceway, a, of independent detachableagitators b and vertically-adjustable governors 0, arranged below eachagitator, substantially as described.

2. The combination, with asluiceway, a, of independent detachableagitators 6, adj ustablc governors c, and independent removable wings(1, arranged substantially as described.

3. An ore-concentrating sluiceway, a, having agitators b, governors c,and wings (I, which are independent and detachably connected to saidsluiceway for removal, to enable the concentrates to be washed outthrough the tail end of the sluiceway and collected thereat,substantially as described.

4. In an ore-concentrator, the combination of the bottom of the sluicewith the agitators I), made narrower than the said sluiceway, andremovable therefrom independently of each other, substantially as andfor the purpose set forth.

5. In an ore-concentrator, the combination, in a sluiceway, ofindependent detachable agitators b and governors c, the lower face ofeach agitator being nearer the upper face of each governor than thelower face of each sluiceway, by bars in and lreys Z, the bars itbeeeeding agitator, substantially as and for the governor is to theupper face of the next suetators being provided with hasps y, engagingstaples h on the sluice, as specified.
